Annotations

The annotation tools are available in 3D Settings.

  1. From your model, go to Settings → 3D Settings or add "/edit" to the end of any model URL.
  2. Select the Annotations panel in the top left.
Only the model's author can access 3D Settings. Edits you make will not change your original file, they will only affect viewing on Sketchfab.

What are annotations?

Annotations are small notes you can stick on your model. They are useful for adding information to a specific part of your model. Each annotation has a position, a camera position, a title (required), and a description (optional). Annotations are ordered in a numerical list.

Here are some Great Annotated Models:

 

This video gives a brief introduction to the annotations feature:

Creating annotations

To create an annotation:

  1. Double-click somewhere on your model.
  2. A circled number appears below the cursor with a text bubble next to it.
  3. The annotation appears in the list on the left hand side of the screen.
  4. Enter a title (required) and a description (optional).
  5. Click anywhere outside the annotation to close it.

Repeat these steps for each annotation and click Save Settings to save them.

Notes:

  • Users with a free account can create up to 5 annotations per model.
  • Users with a PRO account can create up to 20 annotations per model.
  • Users with a Business account can create up to 50 annotations per model.
  • Annotations can only live on the surface of the model - they cannot float in space. As a result, point clouds cannot be annotated.
  • Titles are limited to 64 characters.
  • Descriptions are limited to 1024 characters.
  • Annotations cannot be placed on point clouds.

Deleting annotations

To delete an annotation, click the trash can icon of an annotation in the list on the left hand side of the screen.

Editing annotations

Updating the title or description

  1. Click the annotation in the model view and type your changes in the text bubble.
  2. Click anywhere outside the annotation to close it.

Or

  1. Double-click the annotation or click Edit in the list on the left hand side.
  2. Type your changes in the fields.
  3. Click Done or click outside the annotation to confirm your changes.

Moving annotations

Sketchfab 3d model annotation settings

To move an annotation, drag and drop it to a new position. If the annotation is dragged to a place where it can not be dropped, it turns red.

Updating the camera position

Sketchfab 3d model annotation settings

The camera position is saved when an annotation is created. To update the camera of an annotation:

  1. Set a new camera position.
  2. Click on the camera icon for the annotation in the list on the left hand side.
  3. The thumbnail updates to show the new camera position.

Changing annotation order

Sketchfab 3d model annotation settings

To reorder annotations, drag and drop annotations by their header, up or down in the list.

Viewing annotations

When a model has annotations, new buttons are available in the viewer.

Sketchfab 3d model annotation settings

With these buttons, you can:

  • Go to the previous annotation
  • Open the annotation menu
  • Go to the next annotation

In the annotation menu, you can:

  • Turn annotations on or off
  • Go to a specific annotation
  • Start "Autopilot"

When annotations are off, "next" and "previous" buttons still work and move the camera.

When annotations are off, hovering over the annotation menu button will reveal the annotations.

You can also use the J and K keys to navigate through Annotations.

Autopilot mode will move through annotations at a default speed.

To read an annotation, you can:

  • Click on an annotation
  • Use the "next" and "previous" buttons
  • Click on a specific annotation in the annotation menu
There are also several ways to manipulate annotations with embed parameters.

Saving

Once you've made your adjustments, including position and orientation, be sure to update your model's thumbnail image and default position with Save View and/or save your changes with Save Settings. You can return to your model by clicking either the model's name or Exit.

    Why is not possible the make a reference for another modell on sketchfab in the annotations? It will be a very usefull - killer feature - for presentation of huge modells!

    @SilaS - you could include the short link to another model in an annotation, like this: https://skfb.ly/ArGr

    That was my question, on the killer features note it would be great to click on an annotation and launch into a sectional or interior view of a building

    James

    @moliorarchitects - Thanks for the feedback. Features like that are definitely on our roadmap for the future. At the moment, it's possible with the current Annotations feature to save camera locations for specific views. Check out some virtual tours here: https://sketchfab.com/gerpho

    hello I think annotations are very important for the kind of clients we have, do you have in plan to make them more customizable or with the possibility to add also picture inside etc...this would be very useful for configurator or interactive demo of tools or museum staff

  • Avatar
    James

    @spigolo - yes, adding rich media features inside annotations is on our to-do list. For now you could build something on top of the viewer using the Viewer API.

    Are there any plans for extending annotations to a kind of "public" & maybe user restricted annotation/comment feature for getting feedback on parts of WIP models from clients / colleagues? I'm pretty sure I already saw it in some web based model viewer, but not sure where exactly. Not something I currently need but would keep in mind for future improvements... Maybe when embedded into basecamp/trello etc or also on restricted client websites it would be a nice way of staying on track with the progress of more iterative model designs... :)

    Ok, seems like I mixed up web-based annotation with a new Cinema 4D R16 feature - maybe a suitable inspiration for a sketchfab improvement either way: https://vimeo.com/102543399

    @moritzw - Nice, thanks for the link and feedback. For WIP projects or showing clients privately, you can make the whole model Private?

    Hello!@James:
    Point cloud is not possible to use annotations?

  • Avatar
    moritzw

    @James - I was suggesting a feature where clients can ADD annotations for feedback loops in iterative design themselves. That was my main point :) Regarding private access, I'm sure you guys already have solutions for this availiable :)

  • Avatar
    James

    @mark.energy - Not at the moment! One solution is to manually add some meshed geometry to your model, place annotations on it, then make the mesh 100% transparent.

    @moritzw - Ah I see, thanks for clarifying. https://matter.io/ has an interesting solution to this (and is currently working to improve it), by embedding the whole annotation editor in their site for customers to use.

    moritzw

    Yes, that's what I had in mind. A little database connection for basic comment function by authorized third parties like clients directly in the sketchfab viewport :) Do it! ;)

    Is it possible to upload a 3D model, annotate it, and then "click" on the annotations in Google Cardboard so they display when you want them to?

  • Avatar
    James

    @dcurran - Not at the moment. Annotations + VR mode is something we hope to improve in the future.

    Maybe you could activate "Autopilot" to automatically cycle through the Annotations?

  • Avatar
    dcurran

    @James - Thanks for the response.
    Can you activate "AutoPilot" while in a viewer to turn it on and off? I imagine you would you have to activate it before setting it inside of Cardboard and then take your phone out to stop it?
    Also one more question, I see that AutoPilot is a default timing but can you change the default time?

  • Avatar
    James

    @dcurran - Yes you can, and yes you are correct about starting and stopping it outside the Cardboard, at least for now.

    autopilot

    To change the timing, you'll need to use the URL parameter instead: ?annotation_cycle=X where X is the wait time, in seconds. See this page for details: https://help.sketchfab.com/hc/en-us/articles/203509907-Share-Models#embed-options

    Hey, Is it possible to create or edit annotations? Could not find anything in the API documentation. If there is could I please get the link or some information about it?

    James

    @melledijkstra - It's not possible with the API yet, but it's something we hope to implement in the future.

    Hey, when I update the position of an annotation's camera, how long it takes until it takes effect? I have a scene with 20 annotations (max amount for my currrent profile), I change annotations' camera/view, click "Use current point of view" then save settings. But when I exit editing and go back to the model, the annotations still have the old point of view. What am I doing wrong?

    James

    Hi @urbanid3d - Sorry for the delay!

    Are you still having trouble? Could you send me a link to the model? Thanks!

    @urbanid3d  - Thanks. I went in and changed some annotation views and it worked fine. Are you sure you clicked Save Settings after setting the new cameras?

    If I were to get a Pro account and add more than 5 annotations to a model, what would happen to them if I decide to cancel my Pro subscription? Would the information remain?

  • Avatar
    James

    @Mknight13 - When you downgrade, all your existing content will be preserved, but you won't be able to make any edits to 3D settings - it will show an error that you have too many annotations for your plan.
